4.8 SOFTWARE UPDATE & WIFI
The software update is not possible on the electronic boards. WIFI is not implemented at this moment.
NOTE !
If the filters start t
o get dirty and limit the fresh air passage, before emitting an “over heating alarm E421” the
appliance will start to
limit the energy emission of the POW, a typical call from a customer could be “ the appliance
is not performing any more” or “ after some time the appliance is not performing”.
